From the loop circuits 5 and 5"it would inductively be transmitted to both lines L and L In Fig. 2 are sho'wn arrangementsiorn interconnecting the three linesections L L and L which are substantially similar to those shown in Fig.1 except that the loop circuits 5 and 5, instead of being associated to linesL and L n by the transformer windings 3 and t respectively, are directly con-- nected to the midpoints of the line andnet' 'worlt windings of the hybrid coils '1' and 2.-

Under the:e Conditions speech coming in from lines L and L will be directly applied to the loop circuits 5 and 5 instead of being transmitted through the repeaters R and R As the arran em-ents are in other respects substantially similar to those of Fig. 1, no further description thereof will be given.

In F 3 is shown an arrangement whereby a greater number of lines than three may be interconnected, such, for example, asthe lines L L L and L Lines L, and L, are interconnected by a 22 type repeater in the usual manner. Line L, is connected to another 22 type repeater which is joined by loop circuits 5 and 5' to the first 22 type repeater in a manner similar to that shown in Fig. 1. The line. L, is connected to a third 22 type repeater, which in turn is connected by loop circuits l5 and 15 to the second 22 type repeater in the manner shown in Fig. 2. Under these conditions it will be obvious that all of the lines will be in communication with cach other at once. It desired, other additional lines might also be connected to the lines L L L and L, by providing additional 22 type repeaters andconncciing them to the last of the successive 22 type repeaters by loop circuits either as shown in Figs. 1 or 2.

lVhile the invention has been disclosed as embodied in certain specific arrangementswhich are deemed desirable, it is understood that it is capable of embodiment in many other widely varied forms without departing from the spirit of the invention as defined by the appended claims.

Vhat is claimed is:

1. A circuit for establishing a multi-way telephone connection between a plurality of lines comprising two line sections interconnected by a repeater set, said repeater. set comprising two one-way repeater circuits having thcir terminals connected to hybrid coils, a third line section connected to a second repeater set, said second repeater set comprising two one-way repeater circuits having their terminalsconnected to hybrid coils, and a loop circuit associated with the windings of both of the hybrid coils of said first repeater set and having included serially therein windings of one of the hybrid 6 coils of'said econd repeater set. I

2. A circuit for establishing a multi-way telephone connection between a plurality of lines comprising two' line sections interconnected by a repeater set, said repeater set "comprising two one-way repeater circuits having their terminals connected to hybrid coils, a third line section connected to a second repeater set, said second repeater set comprising two one-way repeater circuits having their terminals connected to hybrid coils and a loop ciicuit inductively connected to the windings of both of the hybrid coils of said first repeater set and having included therein the line and network windings of one of the hybrid coils ofsaid second repeater set.

3. Two 22 type repeater sets, and a loop. circuit associated with the windings of both of the hybrid coils of thc'lirst 22 type rc- 35 peatcr jet and havingincluded serially therein windings of one of the hybrid coils of the second 22type repeater set.

4. A plurality of 22 type repeater sets,

a loop circuit associated with the windings of both of the hybrid coils of the first of said. 22 type repeater sets and having included serially therein, windings of one of the hybrid coils of a second of said 22 type" repeater sets, and another loop circuit asso ciated with windings of both of the hybrid coils of the second of said 22 type repeater sets and having included serially therein windings of one of the hybrid COils ot a third of said 22 type repeater sets.
